Definitions

  • Lintel bars to support brickwork over windows and door openings are a major requirement of the building industry.
  • the most popular conventional lintel bars consis of original mild steel rolled angles of various sizes.
  • Bricklayers are presently often required to support brickwork with steel angles of strengths or dimensions that are imcompatible to the size of brickwork because bars of suitable strength and dimensional size configuration are no readily available. This causes extra work and cost.
  • the conventional angle lintels available do not provide throughout the range, the necessary platform leg length to supply an adequate base width of support to the brickwork.
  • the inside corner of the ordinary angle bar interferes with the edge of the brick and causes the bricklayer to cut the corners off the bricks, which is extra work; or to set the brick clear of the corner radius, thus causing further eccentric loading on the lintel.
  • Figure 1 is a perspective view of a metal bar having deformations to enhance bonding with brickwork to be placed on the lintel bar; '
  • Figure 2 is a transverse cross section taken along the line 2-2 of the bar of Figure 1;
  • Figure 3 is a schematic perspective view of a further lintel bar having projections to enhance bonding with the surrounding brickwork;
  • Figure 4 is a schematic transverse cross section taken along the line 4-4 of Figure 3.
  • the lintel bar 10 is of a generally L-shaped transverse cross section and is deformed at longitudianlly and transversely spaced intervals so as to have projections 11.
  • the lintel bar 10, by being of L-shaped cross section has two legs 12 and 13 which have internal faces 14 and external faces 15.
  • the projections 11 are depicted in the present instance as being provided on the internal faces 14 with corresponding recesses on the external faces 15. However, the reverse could take place o a combination whereby the projections could be located on the external faces 15.
  • lintel bar 20 which is also of generally L-shaped transverse cross section and which is provided with longitudinally extending ribs 21 which are joined by transversely extending ribs 22. Additionally it should be appreciated that the transverse ribs 22, while in the present instance are depicted and described as being formed on the internal faces 23, could b provided on the external faces 24.
  • the lintels 10 and 20 are depicted as supporting a brick 30 with the projections 11 or ribs 21 and 22 spacing the brick 30 from the corners 31 of the lintel bars 10 and 20 such that the corner of the brick does not have to be removed to be correctly located on the lintel bars 10 or 20. Additionally, it is preferred that the effective thickness T of each leg of the lintel bars 10 or 20 be equal or less than the expected mortar thickness employed in standard brick work.
  • the lintel forms a composite beam with the brick work it supports by establishing a sufficient bond with the mortar.
  • This composite beam has the effect of considerably increasing the effective strength of the lintel to the extend that it approximates the strength of a standard lintel bar of almost twice its metal thickness. e.g. A standard lintel bar of 10 mm thickness only slightly exceeds the strength of a present lintel of 6 mm of thickness.
  • the present lintel by being provided externally of the brickwork but bonded thereto, provides a composite beam which is far superior to standard lintels due to its improved bonding characteristics with the brickwork it supports.

Abstract

Une barre de linteau (10) de section transversale generalement en forme de L est deformee sur sa longueur de maniere a presenter des elements en saillie (11) s'etendant depuis des plans normaux definis par les deux jambes (12, 13) de la barre de maniere que la barre (10), en combinaison avec du mortier, forme une poutre composite.
